Nurse-Supported Web-Based Cognitive Behavioral Therapy for Chronic Musculoskeletal Pain: A Randomized Controlled Trial.

BACKGROUND

Web-based cognitive behavioral therapy (CBT) has increased access to effective pain management. Though efficacy of web-based and face-to-face CBT may be comparable, fewer studies have examined whether remote clinical support in addition to web-based CBT can improve pain-related outcomes.

OBJECTIVES

The objectives of this study were to determine if the addition of phone-based support to web-based CBT could enhance pain-related outcomes in patients with chronic musculoskeletal pain (CMP).

STUDY DESIGN

Randomized controlled clinical trial.

SETTING

The internal medicine and rheumatology clinics at Atrium Health Wake Forest Baptist.

METHODS

Patients were recruited from a major academic medical center. Sixty patients were randomized to web-based CBT with 6 phone calls (nurse support group, n = 30) vs web-based CBT alone (control group, n = 30). The purpose of the calls was to enhance patients' engagement in the online program. All patients had access to the program from baseline to week 16. Outcome measures were collected at baseline, week 8, and week 16. Adjusting for baseline measurements, analysis of covariance  was used to determine within- and between-group differences.

RESULTS

Both nurse support and control groups demonstrated significant within-group improvements in Brief Pain Inventory (BPI) pain interference (-1.3 [-2.0, -0.7, P < 0.05] and -1.7 [-2.3, -1.0, P < 0.05]), BPI pain intensity (-1.2 [-1.7, -0.6, P < 0.05] and -1.3 [-1.8, -0.8, P < 0.05]), Patient-Reported Outcomes Measurement System (PROMIS) pain interference (-5.0 [-6.9, -3.2, P < 0.05] and -5.4 [-7.2, -3.5, P < 0.05]), and PROMIS pain intensity (-1.4 [-2.0, -0.9, P < 0.05] and -1.4 [-1.9, -0.8, P < 0.05]), respectively. However, there were no significant between-group differences amongst the 2 treatment groups in all measures, except PROMIS sleep disturbance that favored the nurse support group (50.5 ± 1.3 vs 54.3 ± 1.3, P < 0.05).

LIMITATIONS

Small sample size and lack of treatment fidelity assessment.

CONCLUSIONS

Web-based CBT was effective with and without motivational support from nurses. Phone-based support did not enhance pain-related outcomes of web-based CBT. If confirmed in a larger study, web-based CBT without motivational support may be considered as a low-cost treatment intervention for patients with CMP.
